This'invention relates to an atomizer intended primarily for spraying perfume, medicinal preparations or the like.

The object of the invention is to provide a device of the character stated which is of simple and inexpensive construction but attractive in appearance and which normally constitutes a stopper for the receptacle containing the liquid to be sprayed. Associated with the stopper is a valve which may be turned through a predetermined arc to open the liquid outlet passageway and also a vent Y to the atmosphere. The specific construction of the invention and the advantages resulting therefrom will be explained in connection with the accompanying drawing, in which Figure 1 is a side elevation of the invention.V

Figure 2 is a central longitudinal section thereof.

Figure 3 is a section taken on the line 3-3 of Figure 2.

Figure 4 is a section taken on the line 4-4 of Figure 2.

Figure 5 is a detail perspective view of the valve.

The invention is illustrated in connection with a container 7 which may be of any suitable designand provided with a stopper 8. The inner end of the stopper is provided with a threaded bore 9 adaptedto receive a liquid tube 10 which extends approximately to the bottom of the container 7. The stopper is also formed with a tapered bore 11 disposed transversely to the bore 9 and adapted to receive an elongated rotary valve 12. The smaller end of the tapered bore 11 terminates in a chamber 13 adapted to receive the base of a nozzle 14 which has a threaded connection to the smaller end of the valve 12. A coil spring 15 is seated within the chamber 13 and bears against the base of the nozzle 14 to hold the valve 12 in close contact with the bore 11.

The valve 12 is formed with a central air passageway 16 leading through an air tube 17 to the nozzle and about the tube 17 is a concentric liquid duct 18 also leading to the nozzle and adapted to be placed in communication with the tube 10 when the valve 12 is in q a certain position. A tube 19 is secured to 50 the valve 12 in communication with the air 'passageway 16 and vhas a bulb 20 connected therewith for supplying air under pressureto the nozzle. vThe tube 19 Vmay be of any suitable design, the present embodiment being in the form'ofa gooseneck vso disposed with rela- 55 tion tothe valve that when thev tube and' bulb are in a natural symmetricalposition, that is, when the tube is in a vertical plane' andthe bulb hanging straight down, the valve 12'is Y in closed position. The weight of the bulb also has a tendency to hold the valve in thisv position. l Y f The valve 12 i'sformed withports 21 connectingl the liquid duct18 with "recesses 22 formed'circumferentially'of Vthe valve so that 65 when the valve and tube 19 are rotated to either of the positions shown-'by broken lines in Figure 3, the liquid tube10 is incommunication through `a passageway 23, recess22,

portv 21 and duct18, withthespraynozzle 70- 14, but when the valveis returned to no1- mal .position this communication is out olf.

-Tlie'stopper 8 is also formed with'anair vent 24 extending through thesftoppe'r and intersecting the bore'11'.- In they plane of this 75 air vent the valve 12 is formed with a cir! cumferential groove or recess 25 vwhich is 1 adapted to open the air vent whenever the liquid tube 10 isv 'placed in communication with the nozzle but 'closes such vent'whenever the S0 valve is returned to its normaler closed position. i' i l #From the foregoing description it will be understood that the vtapered valve 12' will normally be held inclos'e contact with the 85 bore11 by the spring 15 and that lwhen the atomizer is'not inuse the bulb 20f-will hang down alongside the container 7 so that both the' yliquid passageway and the air-vent will be closed and the-volatile contents of the .90

container 7 will beV retained without any' loss byevaporation. Whenever theA bulb'20 and tube 19 are swung -to onesidefhowever, the atomizer is ready for operation.

While I have shown:v and described in detail the preferred formfof the invemtion,"it istO''be understood'thatl thesame may beV modified within the scope of theappended claimswithout departing from the spiritl ofrloo the invention.

an air-compressing bulb connected with thc end of the tube remote from the valve, said tube and bulb being so disposed with relation tothe valve that they are in a vertical plane and symmetrical with relation to the stopper only when-the valve is closed. v

In `testimony whereof I have hereunto signed' my name to this specification.
